BESILIENT SUPPORT FOR CUS HION' SEATS.

This invention relates to resilient supports for cushion seats which areespecially designed for vehicle seats, the same being in the nature ofan improvement over our copending application, Serial No. 156,491, filedDecember 22, 1926.

The present invention comprehends a resilient cushion seat support,including a frame defining a compartment for the storage of tools orother articles and which support includes a seat rest which is fulcrumedto the frame in such a manner as to permit of the swinging of the seatrest to an open position whereby access may be gained to the compartmentdefined by the frame for the introduction and removal of articles.

More specifically the invent-ion comprehends a resilient seat supportfor cushion seats, which includes a stationary frame and a seat restmade by a lurality of resilient arms independently fu crumed at theforward ends to the forward upper edge of the frame with a rear crosselement having independent contractile connections with the rear freeends of the arms together with laterally spaced bearings at the rearupper face of the frame within which the rear cross element is normallyseated and] supported whereby the free ends of the arms are tensionedagainst downward'movement and returned to a normal position.

Other objects reside in the details of construction, the simplicity ofthe construction,

the economy with which the same may be produced, and the generalefliciency derived therefrom.

With the above recited and other objects in view",reference is had tothe following specification and accompanying drawings in which there areexhibited or embodiments of the invention which are in no way intendedas limitations uponthe scope of the appended claims as it is to-beclearly understood that variations and modifications which properly fallwithin the scope of said claims may be resorted to when found expedient.

In the drawings-'- Figure 1 is a top pian view of the seat supportconstructed in accordance with the invention;

certain examples relation of the seat rest to the frame, a partially'opened position thereof, and a dc pressed position of the seat rest;

Fig. a is a fragmentary perspective view illustrating the closedsupported position of 'the seat rest in the frame bearings;

Fig. 5 is a sectional view similar to Fig. 3, illustrating aslightlymodified adaptation of the invention.

Referring to the drawings by characters of reference, a stationary frameis designated generally bythe reference character and said stationaryframe includes bottom longitudinal frame strips 11 extending foreand aftor from front to rear, which frame strips are provided with upwardlyprojecting front and rear ends 12 and 13. The front end 12 of each stripis bent inwardly and downwardly to form a bearin knuckle 1 1 and thence.upwardly to an spaced from the end 12 to provide a portion 15, betweenwhich is positioned and bolted the horizontal lead 16 of a horizontalframe strip. From the portion each strip 11 is provided with arearwardly and downwardly inclined terminal 17 havin a horizontalextremity 18 which overlies a race strip19 on each strip 11. The lead 16of the hori zontal frame strip is bolted or otherwise secured by anelement 20 passing through the ends 12, portions 15 and the lead 16. Theextremity 18 is-secured by a bolt 21'or its equivalent to the innermostelement 19 and strip 11. The horizontal upper frame member lead 16 isprovided with rearwardly directed leads 22 at the opposite end of thestationary frame 10, which leads 22 are formed with inwardly bentterminals 23 secured by bolts 24 ortheir equivalent to the rear upturnedends 13 of the longitudinal strips 11. The rear upturned ends 13 areprovided with inwardly and downwardly ent terminals 25 havin horizontalextreme ties 26 secured by bolt/s2 or their equivalent, to the braceelements 19 and the longitudinal strips 11. The bights' or upperportions of the ends and terminals 13 and 25 are downwardly offset toform' open bearings .28 for' the reception of a cross rod 29.

A plurality of arms or fingers 30 constituting a seatrest, are fulcrumedfor inde- Fig. 3 is a longitudinal sectional view pendent movement on across rod 81 mounted in the bearing knuckles 14. Each of the armsconsists of a length or strip of material which is bent substantiallyintermediate its ends to form a loop or eye 32 embracing the cross rod31. The ends of the strip of material form superimposed leaves 33 and34:, which are secured together by bolts 35 or other suitable securingmeans. The arms are transversely spaced by means of spacer leaves 36 onthe front cross rod 31. The arms. or fingers 30 are connected by atransverse semi-flexible strip 37 attached by one set of bolts orsecuring elements 35. At the free rear ends of the arms, the upperleaves ;-.are formed with an upwardlv projecting extremity 38 and thelower leaves 34 with a downwardly projecting .extremity 39. --Thedownwardly projecting extremities 39 are each formed with a rearwardlydirected terminal 40, which is connected to the rear cross rod 29 by acoiled contractile spring 41. The upper ends of the springs 41 arelaterally spaced by spacer sleeves 42. The intermediate spacer sleevesare separated to allow the cross rod to fit within the open bearings 28.A seat S is mounted upon the seat rest defined oy the arms 30, and ispreferably secured thereto. The seat S may have a depending apron Acovering and concealing the seat supporting device.

In practice, the main frame 10 defines a compartment for the receptionof tools or other articles and it is obvious that the seat rest carryingthe seat S may be raised as illustrated in Fig. 3, to gain access to thecompartment defined by the stationary frame 10. In raising the seat, therear cross rod 29 is disengagedfrom the open bearings 28 and when theseat rest is returned to a closed position with respect to the frame10., the rear cross rod 29 is again seated in the open bearings. i t

In the modified adaptation of the invention illustrated in Fig? 5, therear terminal 38 of the uppermost leaf 33 of each arm 30, is extendedupwardly to form a back rest which may be upholstered.

What is claimed is:

1. A resilient support for seats, including within which the rear crossrod is normally seated and supported to anchor the upper end of thecontractile connections, whereby the rear free ends of the arms areten'sioned against downward movement and returned to a normal positionwhen deflected downwardly.
